Some of the less expensive consumer remotes have full learning capabilities, but without computer programming capability there is no way to get these "secret codes" into these remotes. These are codes such as discrete on/off or input codes that don't appear on the OEM remote.

One way around this is to have a more expensive remote on hand, get the codes into it using its programming capabilities, and then teach those commands to the less expensive remote.

I'm thinking though, that there might be a better way. I just bought a Flirc. It's a little USB dongle that plugs into a computer and learns remote control commands using an IR receiver. I'm wondering if that process could be reversed. That is, plug an IR emitter into a computer. Download those secret codes onto that computer, and then teach them to that cheap remote.

Is there any way to accomplish such a thing?

Most remotes made by UEI (One-for-all, some RCA, Inteset, and OEM cable TV remotes) can be programmed with "secret codes" for discrete on/off and input commands directly from the keypad, no computer required (we call them EFCs or magic codes). These remote range from about $3 on ebay to $25 retail. So you could use a cheap remote to teach another cheap remote (or simply replace that cheap remote with a far more functional cheap UEI remote).

I use device called the IR Widget which captures, analyzes and produces codes that can be keyed into a UEI remote which could then be used for teaching. Those remotes can also be programmed or read by a PC via an $8 cable from ebay. That's using JP1 software called Remote Master, IR Scrutinizer and IR Scope. In that case a cheap UEI (JP1) remote could be used instead of a Widget.

IR Scrutinizer may be able to read and translate Lirc format to other formats, but I'm not sure about that. To do what you suggested would require an IR transmitter, which most computers do not have.

IRScrutinizer can do that for you, together with a *supported* IR sender (presently GlobalCache, IrToy, Arduino, wave-device with IR-LEDS, (patched) Lirc server, or IrTrans). It can import most of the common formats, including Lirc.

Thanks for the replies. A lot of information to digest ...
